Harsh Arora's document discusses the Internet of Things (IoT). IoT refers to connecting physical devices to the internet through sensors and allowing them to communicate. IoT devices use technologies like IPv6 for improved mobility, security, and address management across the internet. IoT is useful for applications like low power sensors transmitting data over wireless networks, less congested transportation through smart infrastructure, and automating processes using sensors to identify and fix problems. The key attributes of IoT include sensing via attached sensors, adding intelligence to manual processes, connecting objects to networks, customizing technology for specific verticals, and ubiquitous deployment of devices everywhere. Areas of potential innovation include environment monitoring systems, smart cities, security for reprogramm
